-LRB- CNN -RRB- -- Jarno Trulli and Heikki Kovalainen have kept their places in the rebranded Team Lotus line-up for the 2011 Formula One season .

Italian Trulli and Finn Kovalainen were the line-up for Lotus Racing last season as a team bearing the name of the famous marque returned to the world championship for the first time since 1994 .

The 36-year-old Trulli is preparing for his 15th season in F1 , racing for six different teams , winning his only grand prix in Monaco in 2004 with Renault .

Former McLaren star Kovalainen claimed the new team 's best result in 2011 when he finished 12th in Japan , but suffered a heavy crash in Sunday 's Race of Champions .

He was knocked unconscious and he wrote on his Twitter blog : `` I 've been put to bed-rest at home as a precaution , heavy concussion , further tests in the next few days as head took a big hit . ''

The Team Lotus , who are sponsored by CNN , line-up was confirmed as the sports 's governing body , the FIA , released the provisional drivers ' list for the 2011 season .

Force India , Toro Rosso , Hispania and the renamed Marussia Virgin Racing have yet to confirm their driver line-ups .

Williams announced Tuesday that Venezuelan Pastor Maldonado has been drafted in to drive alongside Rubens Barrichello , although he is not included on the initial list .

He would replace German Nico Hulkenberg , whose contract was not renewed .

Renault have named only Robert Kubica after Russian Vitaly Petrov 's seat was placed into question after an inconsistent first season .

The leading teams of Red Bull , McLaren and Ferrari have , as expected , unchanged line-ups .

Red Bull 's Sebastian Vettel claimed the 2010 world title and paired with Mark Webber to help the team win the constructors ' crown .
